Abstract:
To study the effect of post-harvest treatments such as chitosan (0.5%), chitosan (1.0%), carnauba wax (25%), carnauba wax (50%), Aloe vera gel: Distilled water (V/V) (1:1) and Aloe vera gel: Distilled water (V/V) (2:1) on biochemical changes of different varieties of sapota. Post-harvest treated fruits were stored at ambient storage condition. Traits such as fruit weight, fruit diameter, fruit length, Titratable acidity (%), Reducing sugar (%), Total sugars (%), Non-reducing sugar (%) and Ascorbic acid (mg/100 g) were measured. Among the six post-harvest treatments, Aloe vera gel: Distilled water (V/V) (1:1) fruits were superior in maintaining better physical and bio-chemical parameters even upto 10 days of storage. The maximum acidity, ascorbic acid and minimum of total sugar, reducing sugar and non-reducing was observed in V3C5 (Kalipatti treated with Aloe vera gel: Distilled water (V/V) (1:1)), V3C3 (Carnauba wax 25%), V3C4 (Aloe vera gel: Distilled water (V/V)(2:1)) and V3C4 (Carnauba wax 50%) on most of the days during storage. From the experiment it can be concluded that, post-harvest treatment of sapota varieties Kalipatti and Cricket Ball with Aloe vera gel: Distilled water (V/V) (1:1) and Carnauba wax 25% maintained better physico-chemical characters parameter at ambient conditions. Therefore, application of postharvest Aloe vera gel in the ratio of 1:1 is recommended for improving quality of sapota varieties.
